This invention relates to water-distributing devices such as are used in the fighting of fires or in hydraulic operations, and the object is to provide an improved nozzle-carrying mechanism or gun which offers various advantages in use. In particular in the form of the invention shown the gun may either be mounted in a fixed location for use therefrom or removed and set up at any desired point and freely manipulated in either case.

My invention will be well understood by reference to the following description taken in connection with the accompanying drawings, wherein:

Fig. 1 is a partial side elevation of a fire truck showing a gun embodying my invention mounted on the running board;

Fig. 2 is an enlarged section on the line 2-2 of Fig. 1;

Fig. 3 is a plan of the gun; V

Fig. 4 is a side elevation thereof; and

Fig. 5 is an enlarged section on the line 55 of Fig. 3.

Referring to Fig. 3, the gun herein shown comprises a suitable horizontal length of rigid pipe 7 provided at one end with the coupling 9 by means of which one or more lines of hose or other water conduits may be attached thereto, as, for example, by means of the so-called Siamese 11 shown in Fig. 1. Such a Siamese may be attached to the pipe and remain in position thereon as if a permanent part thereof. The other end of the'pipe is provided with an elbow 13, herein shown as a 45 elbow, which provides a branch normally supported in an upright position, that is, extending upwardly, not necessarily vertically, although the word as herein used includes the vertical as a special case. To the upwardly directed end of the elbow 13 is secured a suitable monitor or universally jointed nozzle carrier herein shown as comprising a Y-shaped fitting 15 connected by means of the swivel joint 17 to the elbow and receiving between its arms the pipe 19, which swings in a plane relatively perpendicular to the plane of movement of the swivel 17 and which carries at its end the nozzle proper 21. At the outer side of the elbow there is preferably provided the groundengaging calk 23 for a purpose which will appear.

The gun as a whole constitutes a portable unit and may be mounted for carriage or for semipermanent use on any convenient structure fixed or ambulatory. By way of illustration I have shown it in Fig. l as mounted on the running board of a fire truck. The support in which it is cradled, as shown in that figure, takes the form of suitable metal stands or brackets comprising a member 25 in which the angularly directed portion of the gun is seated and supports 27 underriding pipe 7. The gun may be secured to its seat by suitable quick-detachable clamping means herein shown as yokes 29 pivoted to the supports 27 and by means of the lever clamps 31 adapted to secure the pipe 7 in position on the latter.

In the position shown in Fig. 1 or when analogously or similarly mounted, the gun may be used by attaching lines of hose to the Siamese 11 and serves the purpose of monitor nozzles installed permanently as a part of a fire wagon. The nozzle obviously may be directed in any direction due to the universal joints of the monitor and the support of the latter on the upturned elbow 13. Mounted on other structures the gun will serve the purpose of a permanent monitor installed on such structures.

The gun, however, constitutes a portable unit which may be quickly removed from its cradle and moved and set up at any desired point. To permit its operation at such a temporary location it is provided with a suitable collapsible stand which may be erected to support it in the same position as in Fig. 1 to permit it to be operated at such new and temporary location with the same efiectiveness. Referring to 3 and 4, the stand is herein shown as comprising gate-like legs 33 secured to or adjacent the elbow 13 to swing about vertical axes 35 and alternatively to lie beside the pipe '7 as shown on the upper side of Fig. 3 or to be swung outwardly therefrom as shown at the lower side.

When the legs are swung to such position they provide in cooperation with the pipe '7 an extended base supporting the gun in the upright position illustrated in Figs. 1 and 4 and preventing it from being tipped over. The gun may be placed and operated anywhere that lines of hose may be laid, for instance, on the roof of a building. Once set in position it may be operated by a single man and the stream may be thrown in any direction without moving body 7 from the ground. This is accomplished by revolving the monitor. In fact it may be revolved in a complete circle, if desired. The stream may be raised or lowered. by moving the pipe 19 up or down. Thus, for example, the device could be placed outside a cellar window and the nozzle pointed downwardly to play a stream into the cellar. The gun may be advanced and placed where men could not stay for any length of time and left there to play its stream.

The legs 33 may obviously take various forms, but, referring to Fig. i, the preferred form herein shown comprises the pivotally mounted body 37 from which extends the horizontal member 39 braced to the upper end of member 37* bythe diagonal 41 and provided at or adjacent its outer or distal end with a ground-engaging call; 43. The calks 43 and the calk 23 on the body of the gun may be pressed into the ground or other surface on which the gun is placed to hold it in position thereon. The legs, or either of them, may be swung out in variable degree to suit the particular needs of the moment.

It will be clear from Fig. 4 that in the arrangement of parts shown the foldable leg is located substantially within the projected outline. of the main body of the gun and when folded up against the same, as in that figure, it is inconspicuous and out of the way. To retain it in folded position a suitable catch 45 (see Fig. 5) may be provided on the pipe 7 herein shown as engaging a portion of the horizontal member 39 When the legs are folded up, they do not interfere with the mounting of the gun in its semipermanent position, as illustrated in Figs. 1 and 2', the legs being there shown as embraced by the clamping means.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive; reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

I claim:
